[Purpose] The goal of this study was to examine the causal relationships between the mental acceptance process of athletic injury and athletic-rehabilitation behavior. the factors of emotional stability and temporal perspective are mediated from the mental acceptance of the injury, which positively influences athletic-rehabilitation dedication. [Summary] The causal model was confirmed to become valid. Key terms: Psychosocial recovery element, Athletic injury mental acceptance, Athletic rehabilitation INTRODUCTION The fields of orthopedic and sports medicine have significantly contributed to the treatment and prevention of sports accidental injuries. A designated advancement in rehabilitation sciences, such as biomechanics and physiotherapy has been seen in recent times, and it has played a central part in the early recovery of sports athletes and return from injury, as well as with the prolongation of athletic life span. However, although these fields dealing with the physical areas of the harmed sportsmen are constantly producing progress, the improvement of mental aspects that directly deal with 1472795-20-2 IC50 sports athletes mental domain has remained sluggish1). Today, rehabilitation is performed during the acute phase. Therefore, the establishment of an intervention model facilitating a prompt shift to treatment, or rehabilitation is needed. In addition, the establishment of a theoretical model that deals with the medical contribution needed for holistic recovery, including shortening the time spent on the physiological and functional recovery of the body is required. In the field of rehabilitation psychology, over the years, the need for a holistic approach that considers the importance of patients psychosocial standpoint has been emphasized. Engel2), a psychiatrist, pointed out that a certain period of time was necessary for the mind to heal, which is the case with all living organisms. In addition, Kbler-Ross model3) was later adopted in various types of rehabilitation. Specifically in the Kbler-Ross model, the natural recovery phases for psychological and emotional aspects were identified, and the need to attend to the dynamics involving psychological intervention were explained. Two different approaches to psychological intervention have been used in the field of rehabilitation medicine. One is the psychodynamic approach based on the theory of loss and grief that has been systematized using Freuds psychoanalysis. The other is 1472795-20-2 IC50 a behavioral approach RDX based on the psychological theory of stress, in which Lazarus and Folkman4) played a key role. These two approaches have developed independently and have made a significant impact on the field of athletic rehabilitation, which is the focus of this study. The first model used in the field of athletic rehabilitation was the stage model (grief reaction model) which is based on the psychodynamic perspective. In general, the stage model is based on the premise that injuries evoke a loss condition for the self5). Within the field of athletic rehabilitation, many studies6,7,8,9) have employed the five-stage model of Kbler-Ross3). Loss accompanies the feelings of sorrow and grief. The stage model formulates the self-defensive and natural coping processes toward such sorrow and grief. This model also deals with the grief of the injured athletes and includes grief therapy with the 1472795-20-2 IC50 goal of psychological acceptance of the injury. However, although clinical psychologists and researchers engaging injured athletes may hypothetically advocate the effectiveness of the stage model7, 8, 10, 11), each stage and its order have not been confirmed by empirical research. With this as the background, doubt has been expressed about the stage model. For example, Brewer12) criticized having less predictive value from the stage model from a demonstrative perspective, and shown a cognitive appraisal model as a fresh theoretical model. The cognitive appraisal model is dependant on the idea of cognitive appraisal for tension and coping suggested by Lazarus and Folkman4). With this theory, a sport damage is undoubtedly a stressor..
